How does interphase prepare cells for mitosis? rest prior to cell division rest prior to cell division growth of cell and replication of DNA growth of cell and replication of DNA breakdown of nucleus and cell membrane breakdown of nucleus and cell membrane division of cytoplasm
Answers
Answer:
Growth of cell and replication of DNA.
Explanation:
The cell cycle has three stages, the interphase, mitosis, and the G0 phase.
Interphase is before mitosis, and it prepares the cell for its division. Interphase has three phases:
G1, where the cell grows in size due to the growth of organelles and components, which the cell will need later. In the S phase, the cell synthesizes a copy of the DNA. The G2, where the cell keeps growing and producing organelles and other elements that will need for mitosis.In conclusion, in the interphase, the cell grows and replicates its DNA.

The structures of the digestive system, aside from the small intestine, that release substances which help to break down food in the small intestine are: C. pancreas and liver.
The digestive system is a body system that consist of structures, organs and gastrointestinal tract for the performance of digestion.
Digestion is simply the break down of food into smaller sizes (fragments) that can be absorbed by the body of a living organism as nutrients while releasing energy through a catabolic process.
In Biology, the organs and body parts that plays an active role in the digestive system are referred to as accessory organs.
Basically, accessory organs of the digestive system include all of the following:
Teeth.Pancreas.Tongue.Gall bladder.Salivary glands.Liver.Generally, both pancreas and liver are essential organs that release gastrointestinal substances which help to break down food in the small intestine of a living organism.

What combination of brightness, carbon dioxide, and water amount results in the greatest sugar production?
Answers
Explanation:
the plant takes in energy from the sun and uses it to change water and carbon dioxide into sugar and oxygen
Through the process of photosynthesis which is used by plants to make energy in the form of oxygen and sugar in the presence of sunlight, water and carbon dioxide.
What is Photosynthesis?Photosynthesis is defined as the process in which solar energy is trapped by chlorophyll which converts carbon dioxide and water into glucose to make food. It is produced in plants where chlorophyll is present inside the chloroplast which initiates the process of trapping solar energy.
It is the main source of food on Earth that releases oxygen which is a vital element for the existence of life. Without photosynthesis, there would be no oxygen on Earth. Chemical energy stored in plants flows to herbivores, carnivores, predators, parasites, decomposers and all life forms.
The process of photosynthesis is written as:
[tex]6CO_2 + 6H_2O ---- > C_6H_1_2O_6 + 6O_2[/tex]
Thus, through the process of photosynthesis which is used by plants to make energy in the form of oxygen and sugar in the presence of sunlight, water and carbon dioxide.

Which statement is true about the layers of the Earth? * 1 as temperature and pressure increases, density increases 2 As temperature and pressure increases, density decreases 3 Temperature and pressure are unrelated to density 4 Pressure and temperature are the only factors controlling density
Answers
Answer:
1. As temperature and pressure increases, density increases
Explanation:
The earth is composed of three main layers: Crust, Mantle and Core. The density or mass per unit volume of the earth's layers increases as one moves from the surface towards the interior of the earth known as the core. Also, there is an increase in pressure and temperature as depth increases. There are three main sources of heat in the earth's core: (1) conserved heat from when the planet formed and coalesced, (2) heat due to friction caused by denser core material sinking to the center of the planet, and (3) heat from the decay of radioactive elements.
The earth's core is composed almost entirely of the metals, iron and nickel. The core has an inner solid layer and a molten outer core. Iron and nickel are both very dense metals, so the core of the earth is very dense and the density increases with depth with the inner core being the most dense layer of the earth.
